Hilary Duff Is Getting Huge!

Awww, sometimes we still can't believe the former Disney starlet is married with a baby on the way!

Today we spotted Hilary Duff leaving her Pilates class (c'mon, where else would she be?), and she flashed photographers a sweet smile before hopping into her Mercedes SUV.

Over the weekend, Hilary's family threw her a baby shower, and it sounds like she was overcome with all sorts of emotions! "What an amazing day my mommy and @HaylieK threw it down!" Hil tweeted. "[B]est baby shower! This baby is spoiled already! And this mama is wiped out!! So grateful for all my friends and family that love and support me through all these huge milestones in my life! Such special memories today!"

The shower took place at Hilary's Los Angeles home on Super Bowl Sunday, and her sister Haylie posted this shot of one of Hil's gifts: A bib that reads, "My aunt is hot and single!"
